Aspheres...Photonics HandbookParticle Image Velocimetry: Basics, Developments and Techniques: New tools and techniques such as single-oscillator, double-pulsed lasers expand the applications for particle image velocimetry, particularly in aircraft design.Particle image velocimetry (PIV) is an experimental tool in fluid mechanics and aerodynamics. The basic principle involves photographic recording of the motion of microscopic particles that follow...Photonics HandbookQuantifying Light: Intensity, Uniformity Hold the Key: When an application requires an illumination source, the designer can provide an optimal solution if the application’s attributes are described in light intensity and uniformity values at the field of interest.Intensity and uniformity can be described using different physical attributes, which makes interpreting requirements somewhat confusing. This article intends to provide an explanation and serve as a...Photonics HandbookNSOM: Discovering New Worlds: Near-field scanning optical microscopy (NSOM) is an optical microscopy technique capable of imaging objects with a resolution below the diffraction limit of conventional (far-field) microscopy; i.e., below approximately half the wavelength of the light used.NSOM is suitable for studies on the mesoscopic scale (several tens to hundreds of molecular dimensions).
